  2. Challenges regarding the Finite Element Method in Bridge Analysis and Design • Strategy to manage changes in the model during the design process • Selection of the appropriate numerical model (i.e. beam, shell or volume-elements?) • Fast traffic load analysis (…time is money) • Reliable design according to various codes and simulation of time-dependent effects • Powerful graphical result presentation • Special investigations in the same environment if necessary (e.g. dynamic wind, nonlinear, seismic…) www.sofistik.com

  13. CABD – Computer Aided Bridge Design • Reference axis as basis Primary axes, secondary axes, variables, placements • Graphical cross‐section input (cross-section editor in SOFiPLUS i.e. based on AutoCAD) • Tendon layout • Traffic loading (Influence line evaluation) • Construction stage simulation (CSR) • Enveloping and Design • Postprocessing www.sofistik.com

  14. CABD - Geometry • Traffic route axes, bridge axes, secondary axes, ... www.sofistik.com

  15. CABD- Variables • Cross section geometry, secondary axes,... www.sofistik.com

  16. CABD- Placements • Important points and sections along an axis Start- and Endfaces, Supports, Construction Joints, Transversal beams, CS jumps • Alignment on primary axis www.sofistik.com

  17. CABD- Structure • Meshing Meshing - Parameters: ctrl MESH, ctrl HMIN, ... • Substructures with reference to an axis respectively placements www.sofistik.com

  18. CABD- Tendon layout • With reference to an axis Prestressing effects for pre‐/post‐tensioning and internal or external tendons Cubic 3D spline tendon geometry Calculation of losses for tendons with 3D profile and curvature Jacking and construction sequences Prestress for beam and shell structures Immediate bond with additional strain in ULS Unbonded tendons Library of prestressing systems Tendon stress diagram Jacking protocol (numerical and graphical) www.sofistik.com
